Abstract

A cable connector is provided for coupling to and mounted within the internal cavity of an electrical box for securing an electrical cable passing through an opening in the electrical box. The cable connector includes a housing having a first end positioned next to or adjacent the cable opening in the electrical box and a second end spaced from the first end and the cable opening. At least one and typically two cable retaining members are positioned in the cable opening of the housing between the front wall and the rear wall. The cable retainer has a body with a plurality of retaining arms extending into an axial passage of the body for gripping the outer surface of a cable.

First claim

What is claimed is:

1. A cable connector for coupling a cable to an electrical box, said cable connector configured for mounting entirely within a cavity of the electrical box, said cable connector comprising:
a housing having a cable opening forming a cable passage oriented for aligning with a cable opening in the electrical box, and a collar on an inner surface of housing, said collar having an axial passage; and
a cable retainer coupled to said housing, said cable retainer having a cable opening for receiving and gripping an outer surface the cable within the cable passage of said housing, said cable retainer configured for sliding transverse to said cable passage between a first position where said cable retainer is not positioned in said cable passage and does not engage the cable, and a second position where the cable retainer is positioned in the cable passage of the housing and axial passage of said collar to grip the cable.

2. The cable connector of claim 1 , wherein
said housing has a front wall and a connecting wall extending from an end of said front wall, and where said cable retainer is connected to said connecting wall for sliding movement with respect to said connecting wall.

3. The cable connector of claim 2 , wherein
said connecting wall defines a top wall extending in a direction substantially parallel to a plane of the cable passage.

4. The cable connector of claim 2 , further comprising
a rear wall spaced from said front wall and having a cable opening aligned with said cable opening in said front wall, and said connecting wall extending between said front wall and rear wall.

5. The cable connector of claim 4 , wherein said connecting member includes an opening for receiving said cable retainer whereby said cable retainer slides between said first position and said second position.

6. The cable connector of claim 5 , wherein said cable connector has a substantially planar portion and said cable opening extends through said planar portion, and said cable opening has an open end, and where said opening in said connecting member is a slot configured for receiving said planar portion of said cable connector.

7. The cable connector of claim 1 , wherein said cable retainer includes at least one arm configured for engaging and gripping the cable, and retaining the cable in the cable connector.

8. The cable connector of claim 1 , wherein said cable retainer includes two opposing arms defining a cable opening between said arms, said arms configured for gripping opposite outer surfaces of said cable when said cable retainer is in said second position.

9. The cable connector of claim 8 , wherein said arms have an inwardly extending tab, and where said cable opening is a substantially circular shaped opening.

10. The cable retainer of claim 8 , wherein said housing has a wall with an opening for receiving said cable retainer, and where said cable retainer slides within said opening between said first position and said second position.

11. The cable retainer of claim 10 , wherein said opening in said wall is a slot, and where said cable retainer has a planar body portion that slides within said slot.

12. The cable connector of claim 8 , wherein said arms of said cable retainer have an end that are spaced-apart a distance to define an open area of said cable opening, said open area having a width less than a diameter of said cable opening.

13. The cable connector of claim 1 , wherein said cable retainer includes planar body having a first arm having an end and a second arm having an end, said ends spaced-apart to form a gap therebetween and having width less than a diameter of said cable opening of said cable retainer.

14. An electrical box assembly comprising:
an electrical box having a rear wall and a side wall, said side wall having at least one cable opening with a dimension for receiving a cable;
a housing coupled to said electrical box and having a cable opening aligned with said cable opening in said electrical box and defining a cable passage for receiving the cable, said housing having a face with an opening; and
a cable retainer received in said opening in said face of said housing and coupled to said housing for sliding movement, said cable retainer having a cable opening for receiving and gripping an outer surface of the cable within the cable passage of said housing, said cable retainer configured for sliding in said opening in said face of said housing in a direction substantially perpendicular to an axis of said cable passage between a first position where said cable retainer does not engage the cable and a second position where the cable retainer is positioned in the cable passage of the housing to grip the cable and receive the cable in the cable opening of the cable retainer.

15. The electrical box assembly of claim 14 , wherein
said housing includes a front wall and said face defines a connecting wall extending from an end of said front wall, and where said cable retainer is slidably connected to said connecting wall.

16. The electrical box assembly of claim 14 , wherein
said cable retainer has a plurality of arms for positioning in said cable passage of said cable connector when said cable retainer is in said second position.

17. The electrical box assembly of claim 16 , wherein said arms of said cable retainer have an end that are spaced-apart a distance to define an open area of said cable opening, said open area having a width less than a diameter of said cable opening.

18. The electrical box assembly of claim 14 , wherein housing further comprises;
a front wall, a rear wall, said face defining a connecting wall extending between said front wall and said rear wall to define said housing of said cable retainer, and where said cable retainer is positioned between said front wall and said rear wall.

19. The electrical box assembly of claim 18 , wherein said cable retainer includes a first arm and a second arm spaced from said first arm a distance to slide over said cable in a transverse direction with respect to a longitudinal axis of the cable, and where said first arm and second arm are spaced-apart a distance to engage opposite sides of said cable.

20. The electrical box assembly of claim 18 , wherein
said connecting wall has an opening receiving said cable retainer whereby said cable retainer is movable between said first position and said second position with respect to said cable passage.

21. The electrical box assembly of claim 14 , wherein said cable retainer includes planar body having a first arm having an end and a second arm having an end, said ends spaced-apart to form a gap therebetween and having width less than a diameter of said cable opening of said cable retainer.

22. A cable retainer for retaining a cable in an electrical box, said cable retainer comprising:
a housing having a front wall with an opening defining a cable passage extending through said front wall, a rear wall spaced from said front wall and having a cable opening aligned with said cable opening in said front wall, and a connecting wall extending between said front wall and rear wall; and
a cable retainer coupled to said connecting wall and being slidable between a first position where said cable retainer does not engage the cable and a second position where the cable retainer engages and grips the cable to retain the cable, said cable retainer including a first connecting arm and a second opposing connecting arm, each said connecting arm having an end and de
